To all whomf it may concern:

Be it known that I, WILLIAM H. Voss, a citizen of the United States, anda resident of Davenport, in the county of Scott and State of Iowa, haveinvent-ed certain new and useful Improvements in Mechanical Movements,of which the following is a full, clear, and exact description.

The object of my invention is to provide improved mechanism forconverting a continuous rotary motion into a rotary reciprocal movementwhich is especially adapted for use in Washing machines and can beoperated easily with a minimum expenditure of effort and greatlymultiply the power applied thereto. This I accomplish by the meanshereinafter fully described,and as particularly pointed out in theclaims.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 isa vertical transverse section taken on dotted line 2 2, Fig. 1, showingthe annulus in one position. Fig. 3 is a similar view showing theannulus in the opposite position. Fig. 4 is a plan view of my improvedmechanism. Fig. 5 is a horizontal section thereof taken on dotted line 55, Fig. 1. Fig. 6 is a longitudinal central section of the same.

Referring to the drawings, A represents a suitable supporting-frame,which is provided with bearings for the continuously-rotatingdrive-shaft B and with a gooseneck A, arising from one of said bearingsand extending in the same direction as said drive-shaft.

C represents the rotary reciprocal shaft, arranged at right angles tothe drive-shaft, which has its upper end journaled in bearings in theoverhanging end of said gooseneck and its lower portion in suitablebearings D in the base-plate or cover, on which said supportingframe ismounted. Just above bearings D a gear E is secured to shaft C, andbetween this gear and the gooseneck a sleeve F is loosely mounted onsaid shaft C, the upper end of which may, if desired, enter the hearingsin the end of the gooseneck and surround and journal the upper end ofthe said shaft. At a certain point above gear E sleeve F has an arm 6projecting therefrom in a direction opposite to the adjacent end of thedrive-shaft, which has an inverted-horseshoe-shaped frame Gr secured toor made integrant therewith, the center of length of which strikesthrough and merges into the sleeve F. The pendent portion of the branchof frame G nearest the drive-shaft is provided with avertically-elongated guide-slot 0, and the opposite extremity of frame Ghas a pendent stud (Z, on which an idle pinion H is loosely journaled.This pinion H meshes with gear E on one side and with a concavedsegmental stationary rack I on the opposite side, which is concentricand is struck from the center of shaft C and is suitably secured to thebed-plate or cover, to which said supporting frame is attached. Motionis imparted to gear E through pinion H as the latter is carried first inone direction and then the other by frame G. In order to impart theproper reciprocal movement to frame G, I pivot to the leg of frame Grfarthest from the drive-shaft the hinged annulus J, the said framehaving a transverse knuckle on its outer surface just below the plane ofarm 6, to the ends of which the pivotal lugs of annulus J are pivoted bya pivotbolt 1'. Diametrically opposite its pivot annulus J has a stud isprojecting inward from it that extends through the guide-slot 0 and hasan antifriction-roller 7t journaled on a pin extending therefrom. Thisantifrictionroller engages an internal elliptical track or cam K, thecurvature of the wall in which said cam is made being struck from thecenter of shaft C and the major axis of said ellipse being horizontal.This track is preferably cast in one piece with the basal flange of thebearings D, and it is arranged transverse to the vertical plane of thedrive-shaft, by which it is intersected midway its length.

The side of the annulus opposite stud it is provided with a segmentalrack N, consisting of a series of equidistant studs whose outer ends areconnected by a segmental rim, and this rack is engaged first on one sideand then the other by a pinion M on the adjacent end of the drive-shaft.

The proportions and dimensions of the cam K, the slot 0, and the rack Nand their cooperative relation are such that rack N is always inengagement with pinion M, and when by virtue of said engagement theannulus moves to the limit of its movement in one direction the pinionengages the end stud of rack N and raises or lowers the said rack andannulus, according to the direction said annulus last moved in, and getsunder and engages the under side of the rack, thus moving the annulus inone direction, or gets above the rack and moves the annulus in theopposite direction. The movement of the annulus is imparted through thehorseshoe-frame G and pinion H to the gear E and shaft C, which rotatesfirst in one direction and then the other.

A mechanical movement comprising a rotaryreciprocal shaft, a gear on said shaft, a stationary segmental rackconcentric with said shaft, an idle wheel interposed between andengaging said gear and rack, rotary reciprocal means for carrying saididle pinion, and a continuously-revolving shaft operatively connected tosaid means.
